I was reading up on SLICK 50 today as it was a product I used in the 80-90’s and it seem by today’s standards it’s not all it was cracked up to be 🤔.. there was a gain horsepower but a restriction in oil flow which is clearly more important . Modern engine oils have all the ingredients to ensure good cold start protection so that makes Slick 50 obsolete ! Back in the day I added slick 50 to a 2.8 celica-supra engine with a noisy tappet from cold, it fixed the problem and never happened again and that was my argument for using it in engine with hydraulic tappets . Not sure synthetic was on the market back then ...maybe if it was that would have fixed the problem for me 👍🏻 Report ..... skepdic.com/slick50.html |

If I remember correctly Slick 50 and STP were really thick and it was that which quietened noisy tappers or even rumbling crankshafts plus many other things. It was commonplace for sellers to put those oils in engines to hide nasty unwanted noises.
But they blocked oilways in some engines. Fords Pinto engine had poor oil feed to the overhead camshaft which resulted in a loud ticking noise ... Folk added those oils to quieten the tick but it was short lived as the ticking got really loud and the camshaft had to be changed.
Quality modern oils don’t need additives ..

I used to use "Wynns" in my older cars. My motorcycles were always a lot newer so I never used it in them.  |

Slick 50 was a thin light coloured liquid and was only promoted as adding extra protection to the engine, unlike Wynns and other brands that Supposedly fixed problems like ..stop smoke, reduce gearbox of diff whine and expanded old oil seal but I always dismissed them ! |

I heard a pair of ladies tights into a noisy diff also quietened them down, the theory was the fibres wrapped around the wurly bits & took up the slack.

That’s sounds very old school😉 ...another favourite of the time was saw dust in the diff to keep it quite to sell 🙄 |

Was that before or after they were pressed into service as an emergency fan belt?  |
